SMA Plug (Male) to TK Jack (Female) RF Adapter | Screw-Lock | Stainless Steel Body
The ROSNOL AD-A1TK25A/9XX-9X is a precision SMA Plug (Male) to TK Jack (Female) straight RF adapter designed for 50 Ω signal transmission from DC to 18 GHz. It features a VSWR of ≤ 1.30 and low insertion loss ≤ 0.05 × √F (GHz), ensuring stable and efficient RF performance. The SMA connector provides compact size, high precision, and reliable performance for high-frequency applications, while the TK connector is designed for robust coupling and dependable mechanical engagement in RF systems. Both interfaces utilize screw-on coupling for secure mating and consistent electrical contact.
Constructed with stainless steel passivated bodies, this adapter offers excellent corrosion resistance and mechanical durability. The center contacts are made of beryllium copper with gold plating over non-magnetic nickel-phosphorus underplating, ensuring high conductivity, low contact resistance, and long-term reliability. PTFE insulators provide stable dielectric performance across wide frequency ranges. Stainless steel construction improves durability and environmental resistance, though with slightly higher cost compared to brass.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
